Is this intermittent? My instinct would be to arrange a service appointment.

Had this problem with our X5 when it was brand new. 12 hours after we picked it up sound started disappearing intermittently. After 3 visits to the dealer trying to reproduce and diagnose the problem they identified it was a faulty amp.

Amps have to come from Germany and took 3 weeks for delivery.

Hope your issue is resolved more quickly and effectively.

I had the same problem on a 2010 750i. The AMP - there even was a service bulletin about it for the 2010. It took a day to fix.

Were one to pay out if pocket, how much is a LOGIC 7 BMW amp?

What is their problem in manufacturing a reliable amp?

I had this problem as well and as stated, this is a common problem noted in the service bulletin.

Any chance you've got the service bulletin info for this?? I've got a 2011 750xi, perfect/beautiful car - but I'm having the same, intermittent problem, with my service department claiming they know nothing of this AND are unable to replicate problem.

Thanks in advance for your help!

Lightbulb LOGIC 7 no audio problem

I sufferred the same problem for about 3 years. After trying to find connection between the problem and potential reason i finally find out that is relating to amount of load in my trunk.
It was lika starting the car with no sound, next start everything working fine, after next start nothing etc.... sometimes it lasts for a week or two, then just start working once, and another few days without sound.

Fault memory was showing AMP int fault or/and AMP overvoltage. Deleting the fault was the cure, but it was really annoing driving 1hr to connect car to the service computer without any guarrantie that it will not stop playing the sound until next start.

For 7 months i was driving with a lot of stuff in my trunk and there was no problem, and some time ago i removed everything and..... it started again.
So the only one logic axplanation was that there are some wires not properly connected.
I decided today to go to service but..... it starts working :o but only for this drive.... so later i went to service to clear the fault memory (that always helped).
How suprised i was that after clearing the fault memory still no sound!!!! and after second check - no fault's at all !!!!
I decided that i have to see how it looks this f...ing LOGIC 7 AMP.
I took this out, all the wires looks ok, but still no sound, and then............... i put my finger on the white wire tape visible thru the ventilation hole and...... just like magic touch..... it starts playing the sound!!!!!!! simple as that. After disassembling the AMP at home, the tape connecting two circut board was U shaped, i changed it to S shape and works fine!!
